You can already get the parameter list of a function using is 
expression.

Smth like:
```
is(func Params == _parameters)
```

But it is a bit buggy, since you have to play a bit with it, 
before you can even extract the values.

Imho, it would be better to improve the is expression rather than 
adding a new trait if possible.
